I would love to have a device that works as flawlessly as the logic analyzer to playback the sampled data. Is there anything like that in the works as Saleae or do you know of other hardware that can?
Thanks for writing this idea in! I edited the title name so we can easily find this idea while we keep an eye on interest. This is something we would love to implement at some point, and is certainly quite unique.
An alternative to this would be the Binho Nova Multi-Protocol USB Host Adapter, which we sell on our website below.
It doesn't have the ability to play back previously recorded signals, however, it's a simple way of generating output data for I2C, SPI, 1-WIRE, SWI, UART, and GPIO.
